Instrumentation
Optional Instrument Panel Gauge Cluster Compass
Calibration Procedure
All new vehicles with an optional compass must have an initial
compass calibration performed. A compass calibration may or
may not have been completed at the vehicle assembly plant.
If the compass headings are noticeably incorrect, or become
noticeably incorrect, or the NO CAL message is displayed, the
Declination Zone may need to be reset to agree with the current
geographic location, or the Compass Directional Calibration will
need to be recalibrated.
The compass direction is displayed in the lower left quadrant
of the instrument panel gauge cluster display just below the
outdoor temperature reading.
Text messages necessary to
calibrate the compass can be found in the instrument panel
gauge cluster display in the lower right quadrant (quadrant 2)
of the display. Twist the instrument panel gauge cluster display
knob until the cursor is flashing in the lower right quadrant.
Press the instrument panel gauge cluster display knob until
the desired text message is displayed. Compass Calibration
related text messages include Calibrate Compass, Compass
Declination, Declination Zone #, and End Calibration.
NOTE: The Declination Zone for the location where the
Compass Calibration procedure is being performed must be
set first and thereafter the Compass Directional Calibration
procedure can be performed. Both procedures are listed
on the following pages and must be followed exactly to
ensure proper calibration of the compass.
Compass Declination Zone Set Procedure
The Declination Zone number is used to account for the
errors between magnetic North and true North in the vehicle’s
geographic operating area, and must be set correctly for the
compass to display accurate headings.
NOTE: When calibrating / recalibrating the compass, you
must select the Declination Zone which corresponds to the
geographic location where the compass calibration is being
performed. It can be reset later to match the Declination
zone where the vehicle will be operating.
For vehicles that regularly operate coast-to-coast or in several
different Declination Zones, either choose a Declination Zone in
the geographic center of the vehicle’s operating area, or change
the Declination Zone daily to match the present Declination
Zone.
To begin the Declination Zone set procedure, the vehicle must be
stopped with ignition key ON. Refer to Zone Map for determining
the proper Declination Zone number.
